If DPR cannot see the difference between the D5200 and D7100 in terms of sharpness, then they are not looking closely enough. And all this talk about "real world" is utter nonsense. If the D5200 and D7100 show a difference in the RAW Comparison, then they will show a difference in general shooting out in the field if both cameras are shot with the same technique, the same lenses and off the same tripod.

If DPR is trying to say that "with handheld snapshots it's hard to see a difference", that totally different than asserting that there is "no difference at all".

And because they say "there is no practical advantage", it's clear that they mean that for snapshots in the park, they can't tell the difference. But it is kind of lame for a testing site to keep using silly caveats like "the real world". What real world is that? Either there is a difference or there isn't. Tests are about empirical data, not general impressions based on what they think real world usage of this camera will be.

But just like D800E out-resolves the D800, the D7100 out-resolves the D5200. And it has zero to do with "best lenses" or any other made up caveat that DPR is trying to sell it's readers. The D800E out-resolves the D800 because it doesn't have an OLPF to blur detail to control moire and the same is true for the D7100 and D5200.
